valve covers blown off

Do you guys remember the guy that said he had his valve cover blown off ? He did not lie, I have a 355 supercharged engine. Knowing that I had two fuel glass low in fule, I tried to start the engine, Big back fire. I blew off both valve covers, the dip stick, and the master cylinder clamp. I also have breathers on both sides of the valve covers, I must check the flote bowls.

I dont really understand how this would happen as the combustion events in the cylinder heads are seperated from what goes on under the valve covers by the valves. Unless you blew through valves I really cant see this happening.

Now I`ve heard of your doors being blown off but the valve covers... Have to see that... If so I`d bet other gaskets like the oil pan and various oil seals cant be in to of shape...?

I was checking for spark one time on a car that wouldn't start and had become flooded. I was checking for spark by holding the end of the spark plug wire by the oil filler hole, (the oil filler cap wasn't on,), The spark worked and it shot a flame about 3 feet out of the hole. Made a big POP too. (kinda sounds like that gas fumes theory might be right)

Singed the hair on my eyebrows.

DOH!

I've seen the valve covers blown off a 3406 Cat. That truck wound up being towed from Texas to the shop in Mississippi.

'57 Chevy - I like that shot of your car.

You should take a picture of that, I'd like to see it. Those are some pretty beefy parts to be chucking through the block. Did the driver mention how many rpm he was actually spinning the thing?
